My partner (who never communicates exept with me, maybe he only exists in my head) is happy with the current prototype of cart/flasher but he is waiting to receive another version of cart/flasher prototype from China (with slow shipping).
Hopefully we will be ready to sell in the next few weeks.

People should take the time before the flash cart releases to find a common game that can be used for its shell—as I understand it, production of new shells is far too expensive to justify. So assuming you don't have any common doubles, this is a good time to hunt for a common game with a ripped up label...

As you saw from my last post we got the redesigned cart produced. It is only layout changes no functional/connectivity changes whatsoever. So it should had run fine, right? Well turns out one of the traces wasn't properly soldered hence the thing doesn't work. Unfortunately due to misunderstanding with the PCB shop, it was a single cart that was produced. Hence we can't check if it's a random problem (those things happen with the PCB production) or a systematic one.

Also there is a delay in producing those, partially due to personal issues that my friend experiences at the moment.

On the bright side, one of the reliability problems that the old revision experienced was due to a software bug in the VHDL code. A change was implemented and briefly tested on the old cart, and it seems to fix the issue.
